Eos Chasma Mensa (Released 14 March 2005)

One of the topics for the Image of the Day was mountains and chaos on Mars.<p>This image is located in Eos Chasma and on the left side contains a feature type called a Mensa, from the Latin word for 'table'. A Mensa is a flat-topped prominence with cliff-like edges. The other isolated hills and mesas are more typical of chaotic terrain - where collapse occurs after some sort of subsurface support material is removed.
